Patented Oct. 31, 1939 UNITED STATES PATENT QFFEQE 2 Claims.

This invention relates to binder canvas slat protectors, and can be used on any machine that uses an apron or reel having slats thereon. One object of the invention is the provision of such a device to protect the slats from wearing out on the ends and from splitting, whereby'the utility and the life of the slats are materially enhanced.

Another object is to provide a protector for binder slats that will prevent the sickle from nicking and breaking the slats.

It is well known that the slats of the binder reel revolve in close relation to the sickle blades. This close relation must exist so that the reel can efiiciently pick up the grain. However, because of this close relation the sickle often strikes the slats, nicking them slowly and finally causing the slats to split, break and wear out. The replacing of the slats takes time as well as being expensive. The present invention eliminates this difficulty and provides the binder canvas slat protector which efficiently protects the slats against damage from the sickle blade and greatly extends the usable life of the slats. The device is simple, may be easily secured in position and is inexpensive.

Briefly stated, this invention comprises a U- shaped steel protecting shield that is secured to the slat by tWo rivets or bolts. The shield has several indentations that prevent it from working loose. The device has several semi-circular cut-out spaces along its edges that fit over the slat frame or supporting arms.

The above and other objects will become apparent upon perusal of the accompanying draw ing, in which the various views illustrate one application of the idea of the present invention, but it is not intended thereby to limit the details of construction of the same to the exact details illustrated except within the scope of the invention, since modifications in form and structure might be made without departing from the spirit of the invention.

Referring briefly to the drawing, Figure 1 is a perspective view of the device applied to a binder slat.

Figure 2 is a side elevational view of the device.

Figure 3 is an end elevational view of the same.

Figure 4 is a cross-sectional view taken on the line 44 of Figure 2.

Figure 5 is a cross-sectional view taken on the line 5-5 of Figure 2.

Referring in detail to the drawing, the numeral Ill represents the protector, and the same is illus trated applied to a slat ll which it is desired to 5 shield by the device. The protector is unitary and U-shaped in cross-section, having the opposed downwardly extending sides IZ. Each side I2 has, at its lower edge, a pair of spaced-apart rounded cut-outs it. These cut-outs facilitate 10 the mounting of the protector on the slat. The slats are usually covered with canvas, not shown.

I In the web M of the device a pair of spacedapart countersunk holes l5 are provided, and they are adapted to receive rivets by means of which 15 the device is secured to the slat. The sides II are provided with a plurality of stamped-in indentations or pins it which dig into the slat and prevent the device from slipping when it is in place. 20

In use, a protector I0 is applied on each slat of the reel or apron by means of rivets or the like, and the protectors will shield the slats from being damaged, as above-mentioned. When a protector has become worn, it may be readily re- 25 placed by a new one.

Obviously, modifications in form and structure may be made without departing from the spirit and scope of the invention.

I claim: 30

1. A device of the class described comprising an elongated U-shaped unitary member having a central web and opposed depending parallel sides, spaced-apart countersunk holes in said web, the device being adapted to be applied to a slat by 35 passing rivets or the like through said holes, the lower edges of said sides having spaced-apart rounded cut-outs therein.

2. A device of the class described comprising an elongated U-shaped unitary member having a 40 central web and opposed depending parallel sides, spaced-apart countersunk holes in said web, the device being adapted to be applied to a slat by passing rivets or the like through said holes, the lower edges of said sides having spaced-apart 45 rounded cut-outs therein, said sides having pointed projections extending inward therefrom.
